A steel bearing pile comprising a beam member of H or I-shaped crosssection having a driving end and a penetrating end, oppositely dis-'Vposed lagging members positioned `between the 15 inner surfaces of theflanges and abutting each side of the web of said beam member, said lagging members each having a straight surface abutting the web of saidbeam'member and an outer surface tapering downwardly fromits .top 20 toits bottom to provide a tapered enlargement on said bearing pile onlyover that portion'of said bearing pile which is in firm load carryingsoil, spaced openings formed in the web of said beam member, means forsecuring said oppositely disposed lagging members together on said beammember, means for protecting the ends of said lagging member adjacentthe penetrating end of said bearing pile and means positioned on the topedges of said lagging member to protect said lagging members, said meansincluding plates on each side ofthe web of said beam member andextending outwardly beyond the edges of the anges, said plates welded tothe web and inner iianges of said beam member and plates supported bythe outwardly extending portions of said rst mentioned plates inparallel alignment with the outer edges of said flanges, said lastmentioned plates welded to said rst mentioned "plates and to the outersurfaces of said flanges of said beam member.
